I think all of this would be fixed if they had a separate button to pull out your knife. Do it like killzone 2 did it. If you hit the melee button with your gun out you rifle-butt/ pistol-whip the enemy (depending on your gun), but it takes like 2-3 hits to kill them this way. However, if you are going into a corridor and you know that there will be melee fighting you can hit a button on the d-pad and pull out a knife, which you can then use to attack and it does more damage. That way no can just push the "insta-kill button" and have everyone in front of the die, since if you want a quicker kill you have to invest the time necessary to actually draw your knife. Honestly though, I want to meet the guy that reasoned and convinced the development team that it was a good idea to add an instant melee kill button that homing lunges at people.
FYI, it is a shit ton better in Black Ops than it was in MW2. MW2 is still the only game FPS game I have played where I could do just as well if not better running around with a fucking butter knife as opposed to shooting people, even though just about every gun was overpowered.
P.S. I have no problem with the knifing kills where the character swipes the knife across the screen, because while they are unrealistic the character at least doesn't lunge at you during which time he's invincible and immune to bullets(yes I know its a videogame, I don't need to hear about how it doesn't need to be or shouldn't be realistic).
P.P.S. If not the killzone way than I also vote to do the way they did it in Reach.
